Acoustic Platforms

From CSL Wiki

Distributed acoustic sensing is one of the early and persistent challenges for distributed sensing. The ability to detect, classify and localize acoustic events of interest over a given area is extremely useful for bioacoustics research.

This page describes the hardware and software platforms we have created to support distributed acoustic sensing.

Experimentation and Demonstrations

Software

EmStar

WaveScope interface glue and network code are in [1]
Drivers for the VXP440 sound card are in emstar/sensors/audiod/vxpc_server
Time synchronization support is in emstar/timesync
The ranging system software is in emstar/devel/loc/ar
The multilateration software is in emstar/devel/loc/multilat
The StateSync multihop routing and coordination primitive is in emstar/devel/state
The diagnostic reporting and control software is in emstar/emproxy (emrun, emview, emproxy and rbsh)

WaveScript

The WaveScript language
The WaveScript compiler is based on Regiment

Firmware: Linux and TinyOS

The ARM development toolchain and the firmware and filesystem patches for the Slauson ARM board are located here.
The firmware for the Mica2 mote (ENSBox V2) is in CVS here and the Linux-side driver is here
